Add 1-2 tsp of water and make batter. Do not add more water as onion in it have moisture. Leave it for 10 mins.

Meanwhile keep oil for frying in high flame.

When oil is hot take a medium lemon size urad dal mixture make a hole in the centre and put for frying.

Fry till golden brown.

Remove and put on a kitchen napkin to drain excess oil.

Now Masala Medu Vada is ready to serve.

You can have with sambar, pudina chutney or any chutney of your choice.

Tips :

Do not put water while grinding. If grinded mixture is watery it absorbs more oil and vada will not come properly. Once you get to know the consistency it is easier to make vadas. Oil should be hot for frying.
